Summary of the invention
The object of the present invention is to provide for determining used when the calculating health status whether reliable method of parameter,
That is, whether measured parameter makes it possible to the calculating being in the main true for cell health state.The purpose passes through basis
Method described in claim 1 is at least partly realized.
According to the first aspect of the invention, the health status ginseng for determining the battery including multiple battery cells is provided
The method of the reliability of numerical value, method includes the following steps: multiple measured parameter values of battery are received, for healthy shape
State parameter；By measured parameter value compared at least one scheduled parameter and standard；And if health parameter value is full
At least one scheduled parameter and standard of foot, it is determined that measured health parameter value is reliable.
Below and should be interpreted in the word " health parameter value " of entire description everywhere can be when calculating
The parameter value used when the health status of battery.Depending on specific battery applications, the health status of battery can be by quite not
It calculates together.And therefore the various methods of the health status of battery are calculated it is well known to those skilled in the art.,
Following description will concentrate mainly in the description for the different parameters of health status that can be used in calculating battery, and not concentrate
On specific calculate.
Moreover, it should be readily appreciated that the present invention relates to the health status ginsengs for determining the completed cell including multiple monomers
The reliability of numerical value, and it is not related to the individual monomer of battery.Battery may include more than such as 50 battery cells, such as
Such as 200 monomers.
In addition, " scheduled parameter and standard " should be understood as can for different types of parameter different standards.
For example, the scheduled parameter and standard of temperature parameter is naturally different compared with the scheduled parameter and standard of voltage parameter.However, predetermined
Parameter and standard can also be different for specific parameter.For example, and as will be described further below, one is predetermined
Parameter and standard can be, monomer temperature cannot be more than certain limit, and another scheduled parameter and standard can be, most hot
Battery cell and the coldest battery cell between temperature difference cannot differ too many.Accordingly, there exist two of temperature parameter
Standard.In addition, specific standard can individually be set by user, and therefore can depend on specific application without
Together.
A kind of method of measurement health parameter value is using Kalman filter, and also referred to as linear quadratic is estimated.
This method is well-known the technical staff in the field of the parameter measurement of the dynamical system of such as battery, thus not into
The description of one step.
Whether the present invention is based on following understandings, reliable for calculating the parameter value of cell health state by determination, can
Realize correctly health status calculated.In addition, the parameter value used when calculating the health status of battery can be due to being permitted
More reasons are unreliable under the certain situations or state of battery, this will be further described below.The present invention is intended to provide right
The parameter measured under these situations or state is classified out as insecure solution.
It is an advantage of the invention that if it is determined that health parameter be it is insecure, then calculated based on this insecure value
Health status will not be sufficiently correct, and therefore according to the method for the present invention determine calculate should not be performed because result will
The reliable expression of the health status of battery is not provided.Therefore, present invention offer determines whether to fit using measured parameter value
Together in the method for the health status for calculating battery.By only when the parameter value done so is reliable, calculating the health of battery
State can carry out the calculating of the time of day of battery being in the main true.In addition, can determine using the present invention, from benefit
The result calculated with the health status of the above health parameter value compared with the result that the user of battery has obtained whether
The relatively reliable and correct estimation of cell health state is provided.Therefore, if it is provided compared with obtained result more
Add properly and securely as a result, can then be determined as calculate cell health state.
Using the present invention, for example, when will increase with the predictability of new battery replacement battery.Therefore, the use of battery
Person will be appreciated by the state of battery and not need for example too early or replace battery too late.Another advantage is the appearance that can be optimization
The operation of amount control battery, for providing capacitance in approximate All Time.This will increase fuel efficiency again and therefore be vehicle
Owner reduce total operating cost.Further, it is also possible to based on the accurately health status fitting Battery service life calculated
Calibration/determination maintenance intervals increase or decrease this interval time section.
According to example embodiment of the present invention, at least one scheduled parameter and standard can be exhausted as derived function dy/dx
The multiple parameter values of the received battery of measurement when being higher than scheduled threshold limit to value, in which:
The measured voltage value of y=battery；And
The state-of-charge calculated of x=battery.
Therefore, if voltage-state-of-charge curve gradient is lower than particular value, it is determined that do not execute the meter of health status
It calculates.This is favourable, because if derived function is zero, or close to zero, then can determine that specific voltage value corresponds to and battery
" correct " state of charge compare too high or too low state of charge.In addition, if gradient is close to zero, then cell voltage
Small increasing or decreasing will lead to sizable increase/reduction of battery charge state, this is so that strong when calculating battery
When health state, be using these values it is inappropriate because the accuracy of state-of-charge calculated is insufficient, it is unreliable that this will be provided
Health status calculating.Preferably, derived function above is applicable to so-called open circuit monomer voltage curve.
It should be readily understood that the known state-of-charge for how calculating battery of those skilled in the art, and therefore will be this
The description of calculating is omitted from description of the invention.In addition, derived function above may cause positive value or negative value, and therefore when true
Whether fixed measured value is reliable so that when in health status calculating, and the absolute value for analyzing these values is important.For example,
For cell voltage value of opening a way, derived function is generally always to provide positive value.
According to example embodiment of the present invention, at least one scheduled parameter and standard can be the mean temperature of battery cell
Within the scope of predetermined temperature.
If the mean temperature of battery cell is too high or too low, may be not suitable for calculating the health status of battery, because
The genuine property of monomer may be described deficiently for temperature value.Therefore, this method determines the health for being not suitable for executing battery
State computation.For example, in the measurement of monomer temperature in the case where carrying out at the time point that battery is charged or discharged, battery cell
Mean temperature can be higher than " normal ".In addition, temperature may be important in particular range, which corresponds to substantially
In the Range of measuring temp when being modeled to cell health state.It is therefore preferred that temperature range should be with Range of measuring temp
It is approximately uniform, mistake is calculated as caused by temperature difference so that reducing.
In addition, other health parameter values may have negative effect to overheat or the battery being subcooled, so if electric
Pond temperature is excessively high/low, this not only makes temperature parameter value itself unreliable, then other health parameter values may also be considered to
It is unreliable.Battery temperature is generally generated by the electric current of battery.Therefore, the deviation of temperature may be electric current flow through battery as a result,
And therefore measured temperature may not provide accurate enough or reliable value.In addition, and as described below, preferably
Ground, temperature measurement should be carried out in the predetermined time period after battery is charged or discharged, to become reliable enough.In temperature
In the case where degree measurement carries out before the end of the predetermined time period after the charge/discharge of battery, temperature " may not be received
Hold back " to its true limit, so that the value measured by these is more inaccurate/reliable.
According to example embodiment of the present invention, at least one scheduled parameter and standard, which may is that, is executing the previous of battery
Charge/discharge after predetermined time period receive measured parameter value.
Therefore, before executing calculating, battery will be allowed abundant " rest ", therefore this makes health status calculated
Reliably.The period shortly after charge/discharge of battery may provide the excessive inclined of the measured parameter of different monomers
Difference, and therefore the reliable calculating of health status is not provided.Therefore, battery is not in stable state.In addition, if measured
Parameter value is, for example, temperature, then if temperature tends to increase/reduction, then can determine electricity during the period for receiving parameter value
Pond is not in stable state.It therefore, can be true if the temperature of battery increases or decreases during the period for receiving parameter value
The charge/discharge for determining battery is performed as being too close to the measurement in time.However, being related to the feelings of battery charge state in measurement
In condition, predetermined time period is not to be exceeded in the period since previous state-of-charge calculates.As described above, state-of-charge
It should be calculated when derived function is "high", therefore, health status calculates should be special after the calculating of this battery charge state
It is executed in the fixed period.If health status calculated after the period of suitable since carrying out state-of-charge calculating " length "
It carries out, then state of charge may not be reliable enough.
According to example embodiment of the present invention, at least one scheduled parameter and standard may is that multiple measured parameters
The value of value is in predetermined range.
Therefore, spreading for measured value must be confirmed as reliably in predetermined range.Often, battery is to height
Temperature and/or low-temperature sensitive, and therefore may not to provide battery strong for the big distribution of the temperature between different battery cells
The sufficiently correct calculating of health state.Distribution between monomer can be for any kind of health parameter, such as
Battery charge state, cell voltage, battery temperature etc..Various parameters will be further described below.
According to example embodiment, scheduled range can be from the measurement of average value of measured parameter value.
Therefore, if the mean deviation of measured value and measurement is too many, can determine should not execute health status
It calculates.
According to example embodiment of the present invention, health parameter can be the monomer temperature of battery, such as receive multiple
Measured battery cell temperature.
As described above, often, battery is to high temperature and/or low-temperature sensitive.For example, temperature between different battery cells
Big distribution may not provide the sufficiently correct calculating of cell health state.When calculating the health status of battery, battery
Temperature is also likely to be the important parameter to be considered, because battery temperature may influence other measured parameters of battery, such as
Such as cell voltage.
According to example embodiment of the present invention, health parameter can be the monomer voltage of battery, so that receiving multiple
Measured battery cell voltage.
Therefore, when calculating health status, possible important further parameter can be used in considering.
According to example embodiment of the present invention, at least one scheduled parameter and standard may is that each battery cell
Measured monomer voltage is lower than scheduled upper voltage limit.
According to example embodiment of the present invention, at least one scheduled parameter and standard may is that each battery cell
Measured monomer voltage is higher than scheduled lower voltage limit.
If cell voltage value is higher than scheduled upper voltage limit or is lower than scheduled lower voltage limit, there is low-voltage
The monomer of value or high-voltage value may damage for some reason.Therefore, calculating cell health state based on these values may
The reliable result of " true " health status of battery is not provided.In addition, measured monomer voltage can be with measured list
The deviation of the average value of bulk voltage compares, and if deviation is excessively serious, can be shown that measured monomer voltage will
Insecure health status value is provided.
In addition, if the difference of monomer voltage is excessively serious between monomer, i.e., in minimum monomer voltage and highest monomer
Range between voltage is more than scheduled voltage monomer scattered band, then there may be the imbalance in battery system, the injustice
Weighing apparatus may by used in the case where not executing balance to battery battery too long or in the case where no use
Battery is set to rest to wait so long and cause.However, it is difficult to conclude with the presence or absence of imbalance in battery system, and therefore may not recognize
It is reliable enough for the result that is calculated from health status, because it is difficult to know the knot of calculating corresponding with the genuine property of battery
Fruit.Therefore, before executing health status and calculating, battery cell needs are adequately balanced.
According to example embodiment of the present invention, the method may further include by means of the received parameter value calculation of institute
The step of state of charge of each battery cell.
Therefore, measured parameter can be used for calculating battery charge state, and therefore hereafter the method can determine
Whether state-of-charge calculated is reliable.Therefore further parameter is provided to be used to determine whether execute the health status of battery
Calculating.
According to example embodiment of the present invention, at least one scheduled parameter and standard may is that each battery cell
State of charge calculated is in predetermined range.
It is as described above it is identical due to, if the state-of-charge of the different monomers of battery exceeds specific range,
Then the calculating of its health status that may indicate battery will not provide the health status of sufficiently exact battery, that is, insecure
As a result.Aspect may also be important for other measured parameters, the state-of-charge of different battery cells is in lotus
The approximately uniform level of electricity condition.
According to example embodiment of the present invention, at least one scheduled parameter and standard may is that is counted with battery cell
The deviation of the average value of the state of charge of calculation is in predetermined range.
According to the second aspect of the invention, the system for being connectable to the battery including multiple battery cells is provided, this is
System includes control unit, which is configured to receive multiple measured parameter values of battery, joins for health status

Specific embodiment
The present invention is more completely described below now with reference to attached drawing, exemplary implementation of the invention is shown in the accompanying drawings
Example.However, the present invention can embody in many different forms and should not be construed as limited to embodiment set forth herein；Phase
Instead, these embodiments are provided for completeness and integrality.It is describing everywhere, identical appended drawing reference indicates identical member
Part.
Referring in particular to attached drawing 1, the vehicle 1 equipped with battery (not shown) is provided.Battery includes multiple battery cells, described more
A battery cell can depend on specific battery mode of operation and be charged and discharged.The vehicle 1 described in Fig. 1 is bus,
The method of the invention for the reliability for determining health parameter value that will be discussed in more detail below is particularly suitable for the bus.
Turning now to Fig. 2, provide for determining the process for calculating the whether reliable example embodiment of cell health state
Figure.Flow chart in Fig. 2 includes: first, this first related with the current accuracy of health parameter value, below
Referred to as parameter accuracy block of state 202；With second, this second is related with the current state of health parameter value,
Hereinafter referred to as parameter state block of state 204.
The non-limiting example embodiment described according to fig. 2, since parameter accuracy block of state 202 comprising:
State-of-charge accuracy state 206；Temperature accuracy state 208；With voltage accuracy state 210.Parameter accuracy state mould
The main purpose of block 202 is when measuring or calculating, and measured by determination or whether parameter calculated is accurate enough.
The state-of-charge accuracy state 206 of parameter accuracy block of state 202 with can calculate battery healthy shape
The accuracy of state-of-charge parameter value calculated used in state is related.The state-of-charge of battery can pass through measured electricity
The combination of pressure value, measured current value or measured voltage value and measured current value calculates.Together with following FIG. 3
Description provides voltage-state-of-charge curve example of the state-of-charge of diagram open circuit monomer voltage curve.Therefore, charged shape
The determination of state accuracy, which depends on measured voltage and or current, to be had mostly accurately.Being described below influences voltage value, current value
And the factor of the combined accuracy of voltage value and current value.
Since voltage value, a conclusive parameter when determining whether voltage value is accurate enough is in charged region
Which kind of state in measure voltage value.These regions will be further described below in relation to Fig. 3.
Influence the accuracy of measured voltage value another parameter be when carrying out voltage measurement, or more specifically, oneself
Since the previous charge or discharge of battery, how long is battery " rest ".Therefore, if since to cell charging/discharging with
Come period within certain periods before carrying out voltage measurement, that is, the previous charge/discharge close to battery when
Between execute voltage measurement, then it is assumed that measured voltage value is more inaccurate.Therefore, measured voltage value with to battery charging/
The electric current of electric discharge relatively changes.If charged with current versus cell, therefore measured voltage value would not indicate battery
Time of day, and thus it is considered unreliable.In addition, voltage value will need after the charge/discharge for executing battery
Time Convergence arrives its " true " value.
In addition, measured voltage value additionally depends on battery temperature at the time of measuring.For example, increased temperature
The resistance of battery will be increased, and therefore, for constant current, provided higher than the measured voltage that may be truth
Value.Therefore, if when a measurement is taken, the temperature of battery in a specific range, is not then not considered as that voltage value is accurate.This
Outside, if the temperature difference between battery cell is not within the scope of specific temperature, measured voltage value could possibly be higher than or
If the voltage value of situation of the temperature in specific range of temperatures lower than monomer.In addition, as described above, carrying out temperature measurement
Period during, the temperature of battery cell does not change too much, that is, preferably, the temperature of metastable state can calculate can
The cell health state leaned on.
In addition, the accuracy of voltage value might also depend on the distribution of the voltage value between battery cell.If most
Difference between polymeric monomer voltage and minimum monomer voltage exceeds scheduled acceptable voltage range, then can determine overall institute
The cell voltage of measurement is inaccurate.
When starting to determine whether measured electric current is accurate, calculated for providing reliable health status, other parameters
It may also be important.For example, its can at the time of carrying out current measurement check battery whether by electric current charge or discharge
It is related.In addition, if measuring electric current when electric current is more unstable, i.e. current measurement is intended to time fluctuation, then it is assumed that electricity
Flow measurement is inaccurate.Another parameter relevant to the accuracy of electric current is the integration current for all battery cells
With.When voltage-state-of-charge derived function is lower than scheduled threshold value, this may to when using the current value of integral for calculating
State-of-charge is interested.Naturally, due to same as described above, temperature is also for determining whether measured electric current is quasi-
True importance.
Finally, determining voltage when whether determine the state-of-charge calculated by means of both voltage and currents is accurate
Combination with the above-mentioned parameter of electric current is may to be accurately important.
Therefore, using at least some above-mentioned parameters, can determine whether state-of-charge accuracy state 206 calculated is sufficient
It is enough accurate.
Temperature accuracy state 208 is gone to, this accuracy state is related with the accuracy of measurement temperature of battery, can
For calculating the health status of battery.As described above, when determine such as measured voltage and current other parameters whether be
When accurate, the temperature of battery can be importance.However, temperature parameter itself also provides in health status calculating, and
And therefore its accuracy for considering to be important before calculating cell health state.
When determining whether measured battery temperature is accurate, there are many aspects that can be considered.For example, if not having
It is supplied to enough sensors of battery, that is, the battery cell of sufficient amount is not provided with temperature sensor, then may think that temperature
Measurement inaccuracy.For example, it may be determined that temperature sensor at least should be provided with every a monomer in order to provide being considered quasi-
True temperature measurement.This is of course depend upon the concrete application of specific battery and battery, may be enough for some applications
It is that every three monomers or even every four monomers are provided with temperature sensor.
It can also be by verifying the difference between the maximum temperature of battery cell and the minimum temperature of battery cell predetermined
In the range of, i.e. being dispersed in specific and received temperature range for temperature and the accuracy of temperature.In addition, another
It on the one hand is that must not differ too many from the temperature of two adjacent temperature sensor measurements.If it is the case, then can be with
Temperature measurement is not accurate enough.Further, the accuracy of temperature sensor itself can also be the aspect to be considered.If
The accuracy of sensor is insufficient, then is therefore not considered as that measured temperature value is accurate.As finally showing for temperature accuracy
Example, if temperature changes with time, variation is excessively rapidly or slow, may be not considered as the temperature carried out during this period
Degree measurement is enough accurately in health status calculating.
It should be noted that often measuring the temperature of battery cell on the surface of monomer or at the electrode of monomer.One is wanted
The further aspect of consideration be the temperature difference between the core of monomer and the surface of monomer whether make on the surface of monomer or
Measured temperature on the electrode of monomer fully describes " true " temperature of monomer.If this may be since to battery charging or
The case where carrying out with being too close in time has been measured since electric discharge.Because monomer core is heated and monomer surface is cooled, institute
To be difficult to assess the genuine property whether temperature measured on the surface describes monomer temperature.Therefore, in order to determine dynamic institute
The temperature of measurement is accurate, it is preferable that measurement should be in utilization/from the certain time after current versus cell charge/discharge
Duan Jinhang.In addition, the core of monomer can have than monomer in the case where battery has been exposed to " serious " charge/discharge
The high temperature in surface takes some time section until the temperature of monomer and the temperature on surface have converged to basic phase after this
Until same temperature levels.
Therefore, using at least some above-mentioned parameters, can determine whether measured temperature accuracy state 208 is quasi- enough
Really.
Turning now to voltage accuracy 210, the accuracy of the measured voltage value of this accuracy state and different monomers
It is related.The accuracy of measured voltage value can depend on specific temperature at the time of measurement.Therefore, if when measurement
Temperature is excessively high when cell voltage, then may be not considered as that measured voltage value is reliable enough or enough accurately with strong when calculating battery
Reliable value is provided when health state.In addition, the other parameters for influencing the accuracy of measured cell voltage be, for example, such as about
What Fig. 3 was further described below, it is measured in which open circuit monomer voltage region, or as described above, since previously right
Period etc. since cell charging/discharging.
Using state-of-charge accuracy 206, temperature accuracy 208 and voltage accuracy 210, it is capable of providing parameter accuracy
Value 212.Therefore, if it is determined that the state-of-charge calculated in 206 be accurately, the temperature measurement in 208 be it is accurate simultaneously
And the voltage in 210 is accurately, it is thus regarded that battery parameter value is accurate.
However, it will be readily appreciated that parameter accuracy value 212 indicate can only by means of state-of-charge accuracy 206,
One in temperature accuracy 208 or voltage accuracy 210 provides accurate battery parameter, to receive the accuracy for indicating battery
Parameter value and to provide all accuracy values be not necessary condition.As described above, different parameters for some application ratios for
It is other more important, and therefore may only consider that the special parameter important for specific application is important.
And turning now to battery status block of state 204 comprising state-of-charge 214, state of temperature 216 and voltage shape
State 218.The main purpose of battery status block of state 204 is to can determine whether the state of battery makes it be beneficial to calculate electricity
Pond health status.Therefore, battery status block of state 204 determines whether the level of parameter value will provide substantially reliable, i.e. base
This accurate health status value calculated.In order to determine battery aging how much, it is measured and calculate battery
Aging used in parameter value need compared with the reference parameter value when battery is new.When battery is new,
The measurement of various parameters is carried out under certain situations, and the situation for determining the parameter of the aging of battery is therefore influenced on record
It is interested, so as to guarantee to provide cell health state calculating reliable result.
Firstly, the state of state-of-charge 214 determines whether the state calculated of state-of-charge facilitates it reliably
Ground health status value calculated, that is, state-of-charge is reliable.For example, if making a reservation for when derived function as described below is higher than
Threshold value when calculate state of charge, then the state of state-of-charge can be determined as reliably.
State of temperature 216 determines whether the state of measured temperature makes it facilitate reliably healthy shape calculated
State value.If the average value of measured temperature is in a specific range, that is, when a measurement is taken, battery overheat or supercooling, then
Measured temperature value can be determined as reliably.In addition, individually monomer temperature should not and battery mean temperature deviation
Too much, to make their value be considered reliable.
Finally, voltage status 218 determines whether measured voltage makes it will be helpful to reliably battery calculated
Health status value.When studying voltage value, if since executing previous battery equilibrium in predetermined time period into
Row voltage measurement then can determine that voltage value is reliable.Therefore, if being dispersed between the voltage value of different monomers is pre-
In fixed voltage range, then it can be seen that voltage value is reliable.The range of research battery cell voltage can be important aspect, because
For for example similar average value can be provided for two measurements, but in highest battery cell voltage and minimum battery cell voltage
Between distribution significant difference between measurements.Therefore, only think the electricity with the monomer voltage spread in predetermined range
It is reliable for flattening mean value.It is therefore contemplated that voltage value is reliable shortly after executing the balance of battery, because flat in battery
After weighing apparatus, the distribution of voltage will reduce.
In addition, if voltage value is too high or too low, it may be considered that voltage value is unreliable.More specifically, if monomer
The level of voltage value is too high or too low, then this may indicate discussed monomer damage.Therefore, when a monomer or multiple monomers
When damage, the health status for calculating battery based on voltage value does not provide sufficiently reliable health status value.
In addition, for the state of state-of-charge 214, state of temperature 216 and voltage status 218, it is also possible to each to determination
The distribution of the value of parameter is interested, that is, how monomer value deviates other monomer values, or how to deviate the calculated average of monomer
Value etc..
Using the state 214,216,218 of battery above, battery status module 220 determines electricity by using above-mentioned parameter
Whether pond state is beneficial to provide reliable health status calculating.
In addition, it should be understood that battery status module 220 not necessarily relies on the whole from various parameters, i.e. from charged shape
The state reception state of state 215, state of temperature 216 or voltage status 218.Due to as described above with parameter accuracy module
The relevant same cause of 212 description, only can be enough from the reception input in module.
Finally, their result is supplied to health status and determined by parameter accuracy module 212 and battery status module 220
Block of state 230.Health status determines that block of state 230 is based on coming autoregressive parameter accuracy module 212 and battery status module 220
Received input determine whether measured parameter value is considered being reliably used for calculating the basic accurate healthy shape of battery
State.
It determines that block of state 230 should receive although Fig. 2 illustrates health status and comes autoregressive parameter accuracy module 212 and electricity
The input of both pond block of state 220, but the present invention should be understood to come autoregressive parameter accuracy module 212 and electricity with only reception
The health status of one input in pond block of state 220 determines that block of state 230 similarly works.
Turning now to Fig. 3 of diagram open circuit monomer voltage curve graph 300.How 300 illustrated battery voltage 302 of curve graph takes
Certainly in the state-of-charge of battery 304.Curve graph 300 in Fig. 3 is divided for five section 306,308,310,312,314.Battery can
By the state-of-charge for showing increased voltage and increased battery arrow 316 represented by be electrically charged, or by showing voltage
Reduce and the reduced arrow 318 of the state-of-charge of battery is discharged representedly.It will be mainly described below by 316 figure of arrow
The curve graph of the battery charge state shown.
In first segment 306, charge from empty state to battery.Therefore, voltage-state-of-charge derived function is relatively steep, that is, with
The increase of state-of-charge 304 is compared, and the increase of voltage 302 is relatively large.On the contrary, first segment 306 indicates electricity when to battery discharge
It pond will be out of power quickly.
In the second segment 308 of curve graph 300, voltage-state-of-charge derived function compared with first segment 306 slightly
Reduce, but the voltage 302 of battery still increases with increased state-of-charge 304, and for its whole volume, electricity
The voltage level in pond is still in its low area.
In the third section 310 of curve graph, derived function defined above is approximately zero.Therefore, battery in this section
State-of-charge 304 still increases but voltage level keeps approximately uniform.
In the 4th section 312 of curve graph and the 5th section 314, derived function has been increased such that cell voltage 302 increases simultaneously
And state-of-charge 304 also increases.In the 5th section 314, the charge level of battery has almost reached to its all told.
Now, as above for described in Fig. 2, measuring voltage value during particular point in time may provide and cannot be recognized
For sufficiently exact parameter value.In Fig. 3, this is illustrated by the third section institute 310 that derived function is approximately zero.More specifically, if
Voltage measurement is carried out when battery charge state is in third section 310, then the accuracy of the corresponding state-of-charge of battery is by phase
To uncertain, because the small variation of voltage 302 will provide the relatively large variation of state-of-charge 304.Therefore, in third section 310
In, it may be difficult to it is provided accurately using measured voltage value, or approximate accurate state of charge, so that measured
Voltage value and state of charge it is inaccurate at third section 310.In the first segment 306 of curve graph 300, second segment 308,
In four section 312 and the 5th section 314, derived function is higher than scheduled received threshold value, and measured voltage value will correspond to
Relatively accurate state of charge.Therefore, the measured voltage value in these sections and corresponding state of charge are recognized
It is calculated to be accurate enough for providing reliable health status.
It is executed at the time point for being beneficial to do so in addition, if state-of-charge is calculated, i.e., in above-mentioned first segment
306, it is executed in one in second segment 308, the 4th section 312 or the 5th section 314, then it can be seen that state of charge is reliable
's.
Although other parameters value can however, measured voltage value and corresponding state of charge are considered accurately
It can cause to be determined as not executing health status calculating.For example, although voltage-state-of-charge is the first segment in curve graph 300
306, in one in second segment 308, the 4th section 312 or the 5th section 314, but the other parameters of such as temperature can have as
This big distribution between monomer is so that determine that this will make health status calculated unreliable.It may cause and do not execute health
The other parameters value of the decision of state computation is provided above in relation to Fig. 2.
In order to summarize the method according to present invention, referring to the example embodiment of diagram according to the method for the present invention
Fig. 4 of flow chart.According to the example described in Fig. 4, the first step S1 of the method is the health measured by the battery receptacle
Status parameter values.For example, measured health parameter value can be in those described above relevant to the description of Fig. 2 and Fig. 3
Either one or two of.Measured health parameter value and the relating to parameters that can be used when calculating the health status of battery.
Hereafter, measured health parameter value S2 compared at least one parameter and standard.At least one described parameter
Standard be described above and can different parameters for battery and different application fields and differently set.
Finally, if health parameter value meets at least one scheduled parameter and standard, it is determined that be good for measured by S3
Health status parameter values are reliable.Therefore, the method can be further determined that based on received measured health status ginseng
Numerical value state health parameters calculating whether can provide accurate result, that is, the result from calculating whether will indicate substantially with
The health status of the corresponding battery of the real behavior of battery.
